BOAT.

SPECIFICATION forming part of Letters Patent No. 757,832, dated April19, 1904.

Application filed May 21, 1902. Serial No. 108,400. (No model.)

To all whom it may concern:

Be it known that 1, JOHN CHRISTOPHER NIoIIoL, of the city of Montreal,district of Montreal, Province of Quebec, Dominion of Canada, haveinvented certain new and useful Improvements in Boats; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

My invention relates particularly to molded boats of the type disclosedin Letters Patent of the United States granted on the 1st of May, 1900,under No. 648,467; and it has for its object to provide a molded boatthe shell whereof is without seam or joining and consists of saturatedfelted fabric. The invention may be said, briefly, to consist in layingupon a mold a blank consisting of saturated felted fabric, drawing theend portions of said blank down over the ends of the mold, and fasteningthem to a part of said mold which is in a position relatively to thegunwale-line to cause the blank to lie taut upon the said ends of themold. The blank is then smoothed tightly upon the mold from the ends tothe midships and fastened to said part for this purpose'as the smoothingprogresses, thus causing all the slack to be taken up and a completeintact felted-fabric shell without seam or joint to be formed. Themolded shell while still upon the mold is then kiln-dried, after whichit is removed from its mold and is ready for lining and furnishing, asusual.

For full comprehension, however, of my invention reference must be hadto the accompanying drawings, forming a part of this specification, inwhich like symbols indicate the same parts, and wherein- Figure 1 is aplan view of the blank from which my improved boat is molded with themold dotted beneath it. Fig. 2 is a perspective View of the blank andmold with the boat partially molded. Fig. 3 is a perspective view of thecomplete molded boat. Fig. i is a transverse sectional view of themolded boat upon the mold, and Fig. 5 is a transverse sectional view ofthe boat removed.

In order that my invention may be clearly understood, it is necessarythat besides disclosing my improved boat itself the method of makingsame should be set forth.

The boat consists of a single piece of saturated felted fabric moldedinto boat form without seam or joint and is illustrated particularly inFigs. 3 and 5.

To construct my improved boat, the blank 6, of felted fabric, is firstsaturated with a solution of shellac or other suitable substance andthen preferably allowed to stand for sufficient time to allow thesuperfluous solution to be absorbed, the time required varying withdifferent thicknesses of felted fabric. The blank is then stretched overthe mold, the ends being first attached by tacks or otherwise to the bowand stern portions of a rail 0 upon the mold (Z and which runscompletely around the mold slightly apart from but upon or within thegunwale-line. After the endsare attached the fabric is smoothed backtherefrom toward midships, as indicated by arrows in Fig. 2, the edge ofthe blank being attached to the rail as the smoothing progresses. Beforethe manipulation or smoothing process has reached Inidships the slackwill have been completely taken up and the felt will be tight upon themold. The boat and mold are then run into a kiln, where the former isthoroughly dried and when removed from the mold is ready for the usualfitting and furnishings. I prefer to set the keel f in a recess in themold and attach the ends of the blank thereto first and independently ofthe attachment to the rail. When the completed shell is stripped fromthe mold, it is not detached from the keel, which remains an integralpart thereof. The complete shell being without seam or joint is lessliable'to leak and more durable than the usual boat-shell and can bemore quickly manufactured.

What I claim is as follows:

1. In the manufacture of a boat first saturating a single sheet of heavyfelted fabric with a resinous substance, then applying said sheet to amold or pattern which contains a separable keel then attaching the endsof said blank to the ends of said mold, thensmoothing said blank uponthe mold from the ends toward midships and attaching the edge of theblank to the mold as the smoothing progresses, then drying said fabricand finally removing it from the mold, substantially as described.

with a resinous substance, then applying said sheet to a mold or patternwhich contains a separable keel, then drawing the ends of said blankover the ends of the mold and attaching same to the ends of the keel,then smoothing said blank upon the mold from the ends to- Ward midshipsand attaching the edge of the blank to the mold as the smoothingprogresses, i

then drying said fabric and finally removing it from the mold,substantially as described.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
